摘　　要：文献上现有的结构分析大多对线荷载作用下的单向板受力性能进行研究,而实际工程中荷载分布宽度无法完全忽略,研究单向板在带状荷载作用下的弯矩分布很有必要。为了能精准确定带状荷载作用下单向板的弯矩分布以及最大弯矩位置,本文导出带状荷载作用下板内弯矩的弹性理论计算公式,并利用MATLAB和ABAQUS对同一算例进行分析,验证了推导公式的合理性。本文给出可快速精确计算带状荷载作用下单向板内弯矩分布的MATLAB计算程序,并提出2种单向板设计建议,最后对带状荷载的分布宽度进行讨论,为结构工程师解决此类问题提供实用方法。The existing structural analysis literature mostly studies the mechanical performance of one-way slab under linear load,but the load distribution width can not be ignored in engineering.It is necessary to study the moment distribution of one-way slab under strip load.In order to accurately determine the bending moment distribution and maximum bending moment position of one-way plate under strip load,based on the elastic theory,a practical formula is compiled.In this paper,the same example is analyzed by MATLAB and ABAQUS to verify the rationality of the formula.The paper presents a MATLAB program which can quickly and accurately calculate the bending moment distribution in one-way slab under strip load,puts forward two design suggestions for one-way slab and the distribution width of strip load is discussed,which provides a practical method for structural engineers to solve such problems.
